This invention relates to car roofs of the According to the present inventiom each type wherein the roof sheets are provided with flanges along their side margins "that extend downwardly into channels orspaces' in carline members. The principal objects of the inventionareto make the jointswater tight, to make the sheets cooperatejwith the carline members in taking care of the stresses due to vertical load, wearingof the car frame and'the like, to devise anew and-improved composite carline, andobtain other advantages hereinafter appearing,

The invention consistsprincipally in clamping togetherthe members ofa comroof at one of the carlines;

posi'te carline with downturned flanges of the roof sheets interposed between saidmembers. It also consists in the parts, combinations and arrangements of parts hereinafter described and claimed.

Fig. 10 is a similar e g onthe fine 10-10inFig.-,7.' I it a modified carline conmain carline member 1 ofsubstantially channel-shaped cross-section which extends from faces of. the side plates. I Preferably thetop of each main carline member 1 extends higherthan the side plates 2 and the endflangese of "said carline member are riveted to said side plates byhorizontal rivets'5'. I

The roof sheets 6 extendentirely across the car and havedownturned flanges 7 at their ends that overlap the "side plates and preferably are riveted thereto by horizontalrivets 8. [Said sheets also have downturned flanges 9 along their side margins which flangesextend into the channels of the main carline members 1, adjacent flanges being somewhat 5 spaced apart. Secondary carline members 10 are interposed between the downturned flanges 9 of the roof sheets 6 and 'areof suitable cross-sectional shape for effectively wedging or locking the sheet flanges and the carline-members together. 7.

In the construction illustrated in Figs. 5

and: 6, the secondary carline member 10 has concave-sides that are well adapted for cooperation with the convex inner walls of'the main channel member 1. In this design of secondary 'carline member, there is acon- 'siderableconcentrati on of metal in the upper portion thereof which is substantially flush with the roof sheets. In the constructionil lustrated in Figs. 9 and '10, the main carline member lahas flat sides and the secondary v carline member-10a is an elongatedsheet or plate folded lengthwiseon'itself with thetwo plies spaced slightly apart and with'the 'opening down. In both cases, theends of the-secf ondary member are spreadoutor widened and turned down, as at 11 and 1 1a,respective- 1 1y, beyond the side plates to which sidesthey are secured by horizontal bolts or rivets, pref:

. the channel member, the flanges of the sheets and the secondary carline members.

In assembling the roof it is desirable to havethe holes for the bolts or rivets 12' so located in the-sheet flanges and secondary carline members that, when the sheets are loosely laid on the carlines, such holes will be slightly higher than the holes in the walls of the channel member; so that, when the rivets or bolts 12 are tightened, they will pull the roof sheets down firmly onto the tops of said channel members. Prior to such riveting or clamping, the void spaces in the channels of the main carline members 1 are filled with suitable plastic cement 13, such, for instance, as that known as reeforite: As such cement is plastic, it permits the metallic parts to betightly clamped together and itself is squeezed or extended into all void spaces in the channels and also fills the angles between the roof sheets and the secondary carline members, thereby not only making a watertight joint but protecting adjacent portions of the sheets from the rusting, corrosion and abrasion to which such portions of thesheets would otherwise be subject by reason of the accumulation thereon of moisture and ciners.

By reason of the carline members and sheet flanges being solidly or rigidly clamped together,they function as a unitary structure in taking care of the stresses to which carlines are subject in service; that is, instead of the channel-shaped member alone constituting a carline with the roof sheets constituting a x load thereon, the marginal portions of the roof sheets and the secondary'members of the carline cooperate directly with the channelshaped' member in taking care of all stresses. Consequently, both the carline members and the roof sheets, or either of them, may be lighter for equal strength than where the carline consists'of channel-shaped members alone. i i What I claim is:

1. A car roof comprising channel-shaped car-line members extending from side plate to side plate, roof sheets on'said members with side marginal flanges extending into the channels thereof, and secondary car-line members between said sheet flanges, all

Y clamped together horizontally.

car-line members extending from side plate' 2.. A car roof comprising channel-shaped to "side plate, roof sheets on said members clamped together horizontally, the space in said channel member not otherwise occupied being filled with cement.

4. A car roof comprising channel carline members secured to the inner sides of the side plates with their tops extending higher than said side plates, roof sheets with side flanges extending into the channels, and secondary carline members between said flanges with their tops substantially flush with said sheets, said carline members and flanges being clamped together horizontally.

5. A car roof comprising channel carline members secured to the inner sides ofthe side plates with their tops extending higher than saidiside plates, roof sheets with side flanges extending into the channels, secondary carline members between said flanges with their tops substantially flush with said sheets,'said carline members and flanges being clamped together horizontally, and said secondary members having widened ends secured to the outer sides of said side plates.

6. A car roof comprising channel carline members secured to the inner sides of the side plates with their tops extending higher than said side plates, roof sheets with side flanges extending into the channels, secondary, carline members'between said flanges with their tops substantially flush with said sheets, said carline members and flanges being clamped together, horizontally, and said: secondary members having widenedends securedto' the outer sides of said side plates,.the space in the channels not otherwise occupied being filled with cement.

7 A car roof comprising main carline members secured against the innersides of the side plates, said members being of channel shape with their side walls convex inward- 71y and with lateral top flanges, roof sheets with side flanges extending into said channels, and secondary carlme'members wltli concave sides, said secondary members being disposed between the sheet flanges and having widened ends secured against the outer sides of-the side plates, said carline members and sheet flanges horizontally. 4

8. A car roof comprising mainfcarline members secured against the inner sides of the side plates,'said members being of channel shape with their side walls'c'onvex inwardly being; clamped together and with lateral top flanges, roof sheets with side flanges extending into said channels, secondary carline members with concave sides, said secondary members being disposed between the sheet flanges and having widened ends secured against the outer sides of the side plates, said carline members and sheet flanges being clamped together horizontally, and the s ace in the channels not otherwise occupied in filled with cement.
